Cassandra Postema, a graduate of London's Central Saint Martins College of Arts and Design, is a fashion designer with a social conscience. From her early days upcycling vintage finds in the British capital and selling them to high-end boutiques, she's had an eye for potential. Since moving to Hong Kong, she has set up a social enterprise, Emi&Eve, which focuses on collaborations with disadvantaged creative types making eye-catching items of jewellery with stories behind them. Her latest collection, From Bullets to Beauty, is a collaboration with a Cambodian who lost his family to the Khmer Rouge. Chantha Thoeunthe specialises in recycling bullets and bomb casings by melting them down and transforming them into unique pieces.
